The removal of tartrazine dye from aqueous solution using g-C3N4/Fe3O4 nanocomposites was studied.The g-C3N4/Fe3O4 nanocomposites were synthesized using simple co-precipitation method. Thesynthesized nanocomposites were characterized by spectral (UV-Vis DRS, FT-IR) and analytical(PXRD, SEM, EDAX, HRTEM) techniques. Photodegradation of tartrazine dye using the synthesizedcatalyst was studied. The g-C3N4/Fe3O4 nanocomposites exhibited excellent photocatalytic performanceby degrading tartrazine (90%) at 0.1 g/L of catalyst and 20 μM initial dye concentration at pH 3. Theexcellent performance by the catalyst was attributed to the highest electron hole pair generation. Thekinetic study revealed that the photodegradation of tartrazine obeyed pseudo first-order kinetics.
